METHOD FOR FOUNDATION CONSTRUCTION UNDER CONDITIONS OF YEAR-ROUND NEGATIVE TEMPERATURES Russian patent published in 2021 - IPC E02D27/35 

FIELD: construction industry.

SUBSTANCE: invention relates to the field of construction and can be used in the construction of a foundation in conditions of year-round negative temperatures. The method for constructing a foundation in conditions of year-round negative temperatures includes the implementation of a prefabricated strip foundation or in the form of a prefabricated panel, which is formed of polyethylene blocks buried in the ground with a plastic lattice frame inside and with protrusions and depressions on the joined walls to perform a “protrusion-depression” type connection. The ground under the foundation is developed to a depth exceeding the height of the blocks, in the developed soil, the foundation tapes are formed. The blocks are joined together with the help of protrusions and depressions on the walls to be joined, and rectangular blocks are used in straight sections, and corner blocks with the corresponding L-shaped configuration are installed in the corners. The polyethylene blocks assembled in the tapes are filled with water, and under the influence of negative temperatures, the tapes made of polyethylene blocks turn into a single ice structure.

EFFECT: invention makes it possible to expand the arsenal of effective technologies for the construction of foundations in conditions of year-round negative temperatures, based on the preservation of frozen soils and providing sufficient load-bearing capacity of the foundation given low labor intensity of the process of its construction.
